Advantech FSP400-70LQ AC-DC Switching Power Supply

Advantech FSP400-70LQ is an AC-DC switching power supply offering up to 400 W of continuous output for industrial control and server equipment. It accepts a wide 100–240 VAC input and delivers three DC rails—3.3 V, 5 V, and 12 V—to support logic circuits, I/O modules, and peripheral devices from a single, centralized source. The multi-rail design simplifies wiring in compact deployments and helps maintain voltage stability across mixed loads in industrial or rack-mounted environments. The FSP400-70LQ is listed in Advantech’s product materials as a 400 W industrial power solution and is based on the FSP Group FSP400-70LQ platform, making it a common choice where a robust, open-frame style AC-to-DC supply is required.
